A "Tractor" daemon consists of a plane with four vertices representing the planes forces. The differences between the individual forces are interpolated to create the force field. Only particles or objects within this field are affected. The daemon’s size is controlled with Node > Scale, though height should not be altered. For this purpose "F1" - "F4" are provided.
Affect
Particles can be affected in two ways: either by “Force” or “Velocity”. The first option applies an external force, resulting in an acceleration, while the second one only modifies the velocities of the particles without introducing an additional acceleration. “Velocity” is not available for rigid and soft bodies.
